Gwen, Pete, and the others have escaped from Everland. But the safe haven they hoped to find at Alnwick Castle doesn't exist. With the Queen of England on her deathbed, Duchess Alyssa has stepped in to lead, but things have gotten worse as the cure Doc created for the Horologia virus has mutated, accelerating the disease. The only possible solution he can think of is to go back to the virus's origin: an extinct poisonous apple.

Legend has it a tree bearing the apple might be found at the center of a deadly labyrinth hidden deep within Germany. A place that no one in their right mind enters. Leaving Pete in charge of the survivors, Alyssa sets out with only her sword, her wits, and the help of Maddox Hadder, a wild boy who oversees the castle gardens. To get to the center of the maze, she'll be forced to battle monsters more terrifying than her darkest nightmares.

But can anyone truly survive the madness of the maze? And what if there's no apple to be found there?

"This patchwork is skillfully stiched together with visible seams that reflect the ragged world the good guys are trying to save. Dark in tone, desperate in intensity, this book will be appreciated by fans of mild horror or those who like dark adaptations of classic tales."
